ment shown herein is particularly adapted for use in autographic registersbut the principle involved and the beneficial results of such an auxiliary feeding device is not necessarily limited thereto.

In the process ofrecording indicia upon the superposed continuous "strips of record stationery, whether in an autographic register or other type of recording mechanism, the pressure applied to the original or topmost strip causes the intermediate strips of carbon paper to become sticky and more "or lessunited to the underlying record strips. Such adhesion of the strips hinders the uniform advancement "of the strip assembly by the feeding means. To overcome this hindrance, excessive pressure of the strip feeding device is required, which possibly greatly exceeds the tensile strengthof the paper in'the'record strips, resulting in a torn or otherwise defaced record form.

To overcome this problem and difficulty, auxiliary or secondary feeding means having "temporary engagement with'the assembly of superposed record strips has been proposed. Most of such units, however, require specially formed writing tables or platens so that the extra feeding means may be accommodated. "Such alteration in the writing tables reduces :the available writing area thereof, however, to a point that in many instances such devices have been found objectionable.

With the present construction a very efiicient secondary or auxiliary feed. is provided without decreasing the available writing area in the recording mechanism, and without complicated and expensive changes in the primary feeding :means or the writing table.

Thus, the object of the present "invention is to simplify the construction as well as the means and mode of 'operation'of astrip feeding mechanism as herein disclosed, whereby such devices may not only be economically manufactured, but will be more efiicient ,and'uniform in operation. adaptable to a wide variety of applications, having relatively few parts, and "be unlikely to get out of repair.

A further object of the invention is to provide an auxiliary feeding device temporarily engageable withthe record strip atlongitudinally spaced points therein.

-A further object of the invention is to provide an auxiliary feeding .device which does 11012116665- sita'te material alteration in the writing surface of the recording mechanism.

A further object of the invention is to provide a writing surface in the recording mechanism of maximum area, comparable to that presentin conventional recording machines of similar types.

A further object of the invention is to provide a reciprocatory strip feeding device actuated in unison with a rotary strip feeding device.

A further object of the invention is to provide a resiliently mounted strip feeding device, intermittently actuated by actuation of the primary feeding device.

-A further objectof the invention is to provide automatic means for withdrawing the auxiliary strip feeding device from the assembly of superposed record str-ips simultaneously with the advancement thereof.

A further objectof the invention is to provide means for automatically releasing the auxiliary feed from the primary feeding means for return to normal position.

'-A further object of the invention is to provide a strip feeding apparatus possessing the advantageous structural features, the inherent meritor ious characteristics and the mode of operation herein disclosed.

'With the above primary and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected :by 'Letters'Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, as hereinafter described .or illustrated in the accompanying drawings, or their equivalents.

Like parts are indicated by similar characters throughout the several views.

The present disclosure represents a further development of that shown and claimed in my copending application Serial No. 593,633, filed May 14, 1945, now matured into Patent No. 2,516,899.

The present invention is shown embodied in a substantially conventional autographic register having a housing I, to the front end of which the cover 2 is pivotally secured. table 3 is pivotally mounted upon the brackets 4 within the register housing adjacent the rear end thereof. Carbon holders 5 carrying strips of carbon 6 are secured to the writing table by means of stationary pins '1, as in the usual autographic register construction. The assembly of superposed record strips 8 are brought from the supply thereof over the strip guide 9, coincident with the writing table mounting, interleaved between the carbon strips 6 and placed in engagement with the transversely aligned pairs of feeding pins at the front of the register.

The pair of outer pins II] are a part of the series of feeding pins located about the periphery of the pin wheels H, fixedly secured to the shaft I2 and actuated by the hand crank i3 to advance the assembly of superposed series connected record forms comprising the strips 8. As is usual practice, the writing table is slotted as at I4, through which slots the pin wheels I I project to engage holes I5 in the superposed strips of the strip assembly and continuously advance the same upon rotation of the pin wheels.

Immediately adjacent the pin wheels I I and inwardly spaced relative thereto are a pair of auxiliary feeding pins I6 projecting through slots H, which slots extend only forwardly from the home position of the pins. Thus, the writing area of the table is in no way reduced, since the table ahead of the home position of the pins shown in Figs. 1, 2 and 3 is not within the area of the record form then in inscribing position.

The auxiliary pins I6 are carried by an inherently resilient spring steel strip I 8 which extends longitudinally of the register, as shown in Figs. 2 and 3. The strips I8 are slidingly secured to the bottom of the writing table 3 by a pair of rivets E9, the reduced shanks of which pass through the elongated slots in the pin carriers I8. The carrier strips I8 are resiliently urged toward the rear of the register, i. e., resiliently maintained in the position shown in Figs. 1, 2 and 3 under influence of the retra'ctile spring 2!, one end of which is secured to the carrier I3 and the other end being fixed to the underside of the table 3, as at 22.

A second auxiliary pin 23 iscarried by the strips I8 at the rear end thereof, i. e., opposite the pin I6. This second pin 23 is so arranged on the strip 18 that it will, when in the home position (Figs. 1, 2 and 3) engage the auxiliary hole 24 in the succeeding form. The same hole 24 is also engaged by the pin I6 when advanced to recording position by operation of the feeding means.

To actuate the auxiliary pins I623 there is provided on the underside of the carrier strip I8 a dog 25 which normally projects into the path of travel of pawl 26 fixedly secured to the pin wheel shaft I2 and actuated in unison therewith The writin .underside of the'writing table 3.

4 under influence of the hand crank I3. Upon forward motion of the pawl 26 (counterclockwise in Figs. 3 and 4) it contacts the dog 25 and temporarily moves it and the associated carrier strip I8 in unison therewith.

Controlling withdrawal of the pins I6-23 and disengagement of the dog 25 from the pawl 26 are a series of cams or control surfaces on the Projecting downwardly from the writing table adjacent the slot I1 and longitudinally aligned therewith are a pair of arcuately contoured flanges 21 upon the curved surface of which the strip I8 bears upon forward movement. As the strip I 8 is moved forwardly by the pawl 26, the flanges engage and deflect the strip, thereby withdrawing the pin I6 from engagement with the hole 24 in the record strips.

The curved periphery of the flanges 21 are not, however, concentric with the periphery of pin wheels H or with the are described by the pawl 28 as it rotates in unison with the pin wheel shaft I2. The inherent resiliency of the carriers I8 causes them to follow closely the contour of the flanges 2'! in their effort to maintain themselves in a single plane. Consequently, as the carrier I8 approaches the forward end of the flange or cam 21, it moves away from the pawl sufficiently that the dog 25 is freed from its engagement with the pawl.

Upon release of the dog 25 therefrom, the carrier I8 is immediately retracted to its original or home position under the retractive influence of the spring 2I where it -remains until a succeeding feeding operation is initiated. The pawl 26, after release from the dog 25, is free to continue its rotation in-unison with the pin wheel shaft I2 through a complete revolution thereof, which is equivalent to the feeding of a full form length.

During the feeding of the assembly of record strips by the pin wheels II after disengagement of the auxiliary pins I6 therefrom, the auxiliary pins remain beneath the surface of the strip assembly. The resiliency of the carriers I8 does not produce suflicient upward pressure against the record strip assembly to cause the auxiliary pins to puncture or otherwise deface the strips.

The auxiliary pins remain in their deflected position under pressure of the assembly of record strips until completion of the feeding operation, at which time the succeeding form length is in writing position. When this occurs, the auxiliary hole 24 in which the trailing pin 23 was previously engaged is in alignment with the forward pin I6, into which hole the pin automatically springs under the influence of the inherent resiliency of the carrier I 8. The feeding device is then conditioned to initiate a succeeding feeding cycle after completion of the inscription upon the record form then in writing position.

The trailing pin 23 is also automatically withdrawn from the record strip assembly as the carrier I8 approaches its forward limit of travel motion under influence of the pawl 26. This is accomplished by embossing or otherwise producing upon the underside of the writing table 3 a control surface or cam 21". The carrier strip I8 is slotted as at 28, within which slot the cam 21' projects. The opposite ends of the slot 28 are downturned providing a pair of ears or cam followers 29 which engage the cam 21 upon longitudinal movement of the carrier I8 to depress the carrier and thereby withdraw the pin 23 from the record strip assembly.

The writing table 3 is also slotted as at to permit sliding movement of the pin 23 relative thereto. Like the slot I? at the front of the table, the rear slot 3 3 is also outside the writing area of the form then in record receiving position, hence does not in any way reduce the available inscription area.

In operation, upon initiation of the feeding operation, there are a plurality of pins in. engageinent with the record strip assembly. Thus, the pull necessary to initiate the advance movement of the strip assembly is divided among the several pins and not concentrated upon the single pin in the pin wheels H. Such additional or auxiliary feeding impulse however, unneces sary after the initial strain is overcome. The auxiliary pins are therefore withdrawn from the strip immediately after the initial strain is overcome. ihe auxiliary pins and their carrier strip are shown in withdrawn position, just prior to return to home position, in Fig. 4. Upon movement of the pawl past the dog it in Fig. i, the carrier strip it is returned to its initial position ready for engagement of the pins lt-23 in the holes 2d of succeeding forms upon completion of the feeding cycle, and return of the pin wheels i i to home position.

While the invention been shown and described in connection with an autographic register, it may be likewise used with fiat bed recording machines, and may be adapted to other forms of writing Or recording equipment.

From the above description it will be apparent that there is thus provided a device of the charactor described possessing the particular features of advantage before enumeratec as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
